Specification of Letters Patent.

HOOF-CLIPPER.

Patented Apr. 2'2, 11215.

Application filed. May 25, 1914. Serial No. 840,693.

To all whom it may concern Be it known that I, ROY L. ARTHUR, a citizenof the United States, a resident of Lane, in the county of- Dewitt andState of Illinois, have invented certain new and use ful Improvements inHoof- Clippers, of which the following is a specification.

My invention relates to improvements in hoof clippers, and has for itsprincipal object the provision of such a device which is simple inconstruction, easy to operate and eflicient in producing good results inthe hands of an experienced workman.

A further object is the provision of a hoof clipper in which the knifecooperating jaw is first moved under the hoof of an animal, and then theknife forced downwardly to clip the hoof.

Further objects include improvements in details of construction andoperation.

To the accomplishment of the foregoing and such other objects as mayhereinafter appear, my invention consists in the construction,combination and arrangement of parts hereinafter described and thensought to be defined in the claims, reference being had to theaccompanying drawings forming a part hereof, and which show forillustrative purposes a preferred embodiment of my invention, it beingunderstood however that various changes may be made within the scope ofthe claims without digressing from my inventive idea.

In the drawings :Figure 1 represents a side elevation of a deviceconstructed according to my invention in position ready to beginoperation; Fig. 2 is a similar view of the operating parts at thecompletion of their operation; Fig. 3 is a view similar to Fig. 1, ofthe other side of the device.

Referring now to the drawings, the numeral 1 designates one of thehandle members which forms or constitutes what might be called a basemember, having its end provided with the enlarged transverse member 2,having the sharpened lower edge 3 and depending extension l for thepurpose of providing an anchorage or bearing for the device when inoperation, as will be explained later. This handle member is providedwith a longitudinally extending slot 5, intermediate its ends, and hasits other end bifurcated or forked as at 6, to receive a portion of theother handle or operating member 7. Mounted so as to slide relative tosaid handle or base member 1, is the knife carrying member 8, having thespaced side members 9 extending along said handle or base member, whichare connected by means of a pin 10, which is loosely slidable in slot 5.The head of this member 8 is provided with the knife member 11, asshown. The handle member 7 is pivotally connected to this member 8 bymeans of the pin 12 which passes through the boss or sleeve 13, on theend of said handle member 7. A pm It passes through the bifurcated orforked ends 6 of the handle or base member 1, pivotally connecting it tosaid handle member above the boss or sleeve 13. The handle member 7 isthen bent to extend at an angle, as indicated at 15, and to this portionis pivotally connected, as by means of pin 16, member 17 which carriesthe jaw or blade to cooperate with the knife 11. This member 17 has itsend bifurcated as at 18, to embrace the inclined portion 15 of thehandle 7, and the pin 16 passes therethrough, forming a pivotalconnection. The lower portion of this member 17 is formed of peculiarshape as shown in the figures of the drawing having its one face formedon a double curve providing seat 19 and the inclined portion 19 whilethe other face has the two inclined portions 20 and 20. The foot 21 hasthe knife memben 21 attached thereto,

the latter being preferably of drop forged steel while the member 17 isof malleable casting. The pins 22 are secured to member 8 and positionedon opposite sides of the lower portion of member 17. These pinscooperate with the above described surfaces of the member 17 to producethe proper movement and coaction between the knife carrying members aswill be described later.

Secured to the pin 16 is the pruning knife member 23 which is pivotedintermediate its ends on pin 12, having the lower portion formed withthe convex knife edge 2 which cooperates with a correspondingly curvedconcave portion 25, on the adjacent side member 9, of member 8. Thisprovides the pruning knife or tree trimmer.

Apertures 26 and 27 are provided in the handle members 1 and 7 for thepurpose of v attaching extensions to facilitate the operwith the foot ofthe operator on the rear portion of the base member 1, thus forcing theextension l' into the ground to anchor the device. The 'handle member 7is then moved downward, which operation first causes the knife member21, 21 to move forwardly under the hoof of the animal, this movementbeing caused by the engagement of the pin 22 with the inclined surfacelead ing from seat or recess 19, it being noted that member 17 ispivotally connected to handle 7. lVhen this pin passes the apex 19", theknife 11 is caused to descend rapidly in a substantially verticaldirection, andwill clip the hoof of the animal.

jThe operation of the device as a pruning knife .or tree trimmer isobvious. The simplicity of structure renders the article cheapto'manufacture and eflicient in operation.

What I claim is,

1. In a device of the character described and in combination, a pair ofhandle members pivotally connected together, one of which forms. a basemember, a knife carrying member having a slidable and pivotal connectionwith one of said handle members and a jaw or anvil member pivotallyconnected to the other of saidzhandle members and adapted to cooperatewith said knife carrying member, said jaw or anvil member having oneface formed'on two inclines converging to an apex and a pin connected tosaid knife carrying member engaging said face whereby a slidable andpivotal connection between said members is provided.

2, In a device of the character described and in combination, a pair ofhandle members pivotally connected together, one of which forms a basemember, a-knife carrying member having a slidable and pivotal connectionwith one of said handle members and a jaw or anvil member pivotallyconnected to the other of said handle members and adapted to cooperatewith said knife carrying member, said jaw or anvil member having itsedge faces each formed on a plurality of inclines and a plurality ofpins connected to said knife carrying member and positioned on oppositesides of said jaw or anvil member to engage said edge faces thereof,whereby a slidable and pivotal connection between said members isprovided.

8. In a device of the character described and in combination, a pair ofhandle members pivotally connected together, one of which is adapted toserve as a base member, a knife carrying member having a slidable andpivotal connection with said base member, the other of said handlemembers also having a pivotal connection with said knife carryingmember, said knife carrying member being formed with spaced side membersand a pin connection at the ends of said spaced side members to saidbase member to form said slidable and pivotal connection, a jaw or anvilmember extending between said spaced side members of said knife carryingmember and pivotally connected to the other of said handle members, saidjaw or anvil member having its edge faces each formed on a plurality ofinclines and a plurality of pins connected to said knife carrying memberand positioned on opposite sides of said jaw or anvil member to engagesaid edge faces thereof, whereby a slidable and pivotal connectionbetween said members is provided.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.
